, and are all intriguing options for new general manager Jon Robinson with the No. 1 pick of the , but nothing creates intrigue like a trade.And if Robinson is in the mood to deal, NFL Media analyst -- and former general manager of the and -- Charley Ca serly offered his playbook for moving out of the draft's top spot."The first thing you do when you trade back is you decide, 'How far are you going to go back?' To me, there are four players I think I'd take with the first pick in the draft. (Tunsil and Bosa are two) Jalen I think is worth it, and I think is worth it," Ca serly said on 's "Path to the Draft". "So I'm not going to go back any farther (than No. 4) so I'm not going to lose one of those guys."Making that determination, however, Ken Landreaux Jersey is just one task if Robinson decides it would be in the ' best interest to move down. The other, Ca serly said, is to drive up the price clubs will pay for the pick."How do you create a market when there isn't one? ... No. 1, I'm getting calls. People want this pick. You keep wearing them out on that. Then you do off-the-record interviews in the cities of the teams you want to trade for, and plug the quarterbacks hard. You make them sound like they're the second coming," Ca serly suggested. "The media will eat it up and they'll start a groundswell to try to pre sure the team to go get a quarterback. Then you go to the agent. The agents for the quarterbacks want them to go No. 1, so they're going to start saying, 'Hey, you better go to No. 1 to get this guy, or you're not going to get him."Translation: smoke screens are real, and so is their effectivene s.Of course, all the smoke in the world wouldn't help Robinson sell the notion that he's interested in a quarterback himself, not with second-year starter having just been taken No. 2 overall a year ago. As such, the can comfortably a sume they can get their choice of quarterbacks with the No. 2 pick.For any other club, however, there are no guarantees without dealing with Robinson.*Follow Chase Goodbread on Twitter *.
